EDGAR G. FRELINGER, OF FORT THOMAS, KENTUCKY.

BARREL AGI'IATOR.

Application, filed January 29, 1821 Serial No. 441,063.

T 0 all whom it may concern:

Be it known that I, EDGAR G. Fnnnrnonn,

a citizen of the United States, and resident of Fort Thomas, in the county of Campbell and State of Kentucky, have invented certain new and useful Improvements in Barrel Agitators, of which the following is a full, clear, and exact description, reference being had to the drawings forming part of thisspecification. V

My invention-relates t0 agitatorsrfor stirring up the material that'settles tothe bottom of barrels of p'aint, varnish, and the like, and generally known to the trade as barrel agitators. I v

. In barrel agitators ofthe past, whatever be the mounting provided for them, or however they may be insertedin the barrel, there are a few defects present which should be avoided. Among these are: ineffectiveness to the'agitator itself or location of it I at too great a distance from the base of the barrel; tendency of the agitator to rise up in the barrel when being reversed; tendency of the agitator to scrape the base of the barrel or the sides and thus get out of shape itself and deteriorate the barrel; difliculty of mounting the operating rod for the agitator in the barrel without an expensive construction. y The object of my 'invention is to avoid the various defects in prior structures and generally to provide a construction of agitator which is strong, inexpensive, and eliicient for the purposes to which it may be applied and which can be asse'mbledin or removed from the'barrel' or receptacle without removing; the heads or staves of the barrel, and without making any holes in the barrel which are not normally present therein. a a

Among other things I provide an agitator In the drawings,

Referring in detail to the drawings, 1 indicates a barrel of usual shape and construction, with heads 2 and 3 and a bunghole 4. An opening 5 is drilled in the cen ter of the head 2, and also in the base 3 when the part shown in Figure 8 is used.

The bearing 6 consists of a metal casting, stamping or forging having an enlarged central chamber or socket 7, having an opening 8, with a slightly constricted outer margin at 8* to receive the shaft end and a much smaller opening 9 below to receive a screw 10 by which it is fastened to the inner side of the bottom3. Otherwise (Figure 8) the 1 bearing may be castintegral with a plug 6, which is-mount'ed in a holein the base of the barrel. e

, The diameter ofthe bearing 6 is slightly less thanthe hole 5 in the head and to secure the; bearing in the bottom of the barrel,

1 the casting is passed through the hole 5, the

tormedot a folded strip of metal'whichpresents upwardly-slanting sides at all portions thereof and a push button form of operating rod mounting in theibase of the barrel which permits of easy insertion and withdrawal. The strip may be of any type of constructiom-however, and I do not wisht limit myself to sheet metal parts. My invention consists of that certain novel construction and arrangement of parts to be hereinafter more specifically pointed out and claimed. a 1

screw-1O being located in place. Then with a long screw driver, inserted through a pipe or tube, the screw is drivenhome m'the bot tom 3. The shaft 11 is preferably rectangular in cross section with a ball 12 at one end, this ball being split as at 13 to give it the necessary resiliency to allow it to be driven through the opening 8 and into the socket 7. The diameter of the ball is such that while force is required to insert it through the opening at 8, it will operate freely in the socket 7. While the ball 12 is wholly received in the socket 7, the reduced portion 14 between it and the rest of the shaft lies in the opening 8.

The agitator '15 is constructed of a wide strip of sheet metal bent longitudinally to form a channeled member, and invertedV- shape in cross section or the bottom may be oblong opening 21 in the top center of the blade. The blade is formed up around the portion 19 and the corners 19 of this said portion are rounded off to maintain a round ed edge for the agitator throughout and not to interfere with insertion of the same through the bunghole of the barrel.

v A threaded ca 22 closes the opening 5 in the bar-rel when the device is not in use or while shipping. This cap is'recessed at 23 to receive the projecting end of the shaft 11 so that once it is mounted It'ClOBS not require.

removal.

The agitator may be operated by means of a suitable cranh fitted to receive the projecting end of shaft 11, or by other mechanical power transmitting devices-attached to the shaft.

The crank shown has a socket member 11 of a size to fit the ball of the hole 5 in the barrel and a handle 11. The socket guides and steadies the crank when in use.

The ball end of the shaft 11 may at any time be inserted through the head-hole and so held 7 I that the shaft will pass throu-glrit at 20.

The shaft is then thrust down i-iln'til it comes in contact with opening 8 in the bearing 6;

Pressure exerted upon the projecting end of shaft 11will now, drive ball 12 through the opening '8 into the central chamber or socket 7 of bearing 6. r

It will be noted that the upper end of the socket or hearing member is beveled off as at "21 and that the central core piece lIl-tl'le agita-tor blade hasa countersunk portion which it over this beveled portion,thereby permitting the base of the agitator blade to come down veryfclose to the bottom of the barrel;

The fact thatthea itatin surfaces J of the doublewall agitator, now described, all face upwardly, the said agitator will always he held down against the hearing or socket at the base of the barrel and when revolved in either direction will force upwardly into the barrel all heavy matter settled to. the bottom of the barrel contents. The end blocks in the agitator will rub on the base of the barrel, should. tipping take place, thereby saving the agitator and the bottom of the barrel. V j

The blade thus be made npcheaply of sheet metal, and the three inexpensive castings within the-body of the blade areeasily mounted and will not add greatlyto theexpense. The snap button structure of the shaft bearing and shaft end, provides a simple, inexpensive and'secure method of mounting the shaft revolubly in the barrel and here again the tendency of the agitator to stay at the bottom ofgthe barrel relieves me of the necessity of providing-any complicated or expensive shaft hearing which will prevent accidental jumping of the shaft out of its bearing due topressure of the agitator. during its work. 7

Having thus described my invention, what 1 claim as newland desire to secure by Let ters Patent, is
